An age-normed test battery was developed for use as a research instrument to assess strengths and weaknesses in the sensory-motor development of elementary school age children. The importance of sensory-motor functions for the child's total development and learning is noted. The experimental sensory-motor test battery consists of 12 subtests, and requires approximately 20 to 25 minutes to be administered to an individual child; however, a group of three or four children can be individually tested in about 45 minutes. The subtests are administered in the following order: 1. bead stringing, 2. first-edge-palm, 3. block transfer, 4. bean bag throw, 5. sitting, bending, reaching, 6. standing broad jump, 7. shuttle run, 8. lying on floor to standing position, 9. sit-ups, 10. walking board, 11. one foot balance (eyes open and eyes closed), and 12. chair push-ups. The standardization sample consisted of 744 Caucasian children, 6 through 12 years of age, from Kindergarten through Grade 6. The major evidence at present concerning the validity of the instrument was provided by the factor analysis of the intercorrelations for each age group. The five factors were interpreted as: "hand-eye coordination,""balance,""explosive strength or impulsion,""flexibility," and "visually guided movement." The minimum estimates of internal consistency reliability of the subtests range from .44 to .88. (Author/DB)
